In the arrangement shown the electron multiplier comprises a number of perforated secondary electrodes 15 ... 19, as described in Specification 516,621 provided with auxiliary electrodes 22 as described in Specification 531,541. The cathode 10 is formed with an enlarged head 11 co-operating with the electrode multiplier and the body of the tube is surrounded by a grid 23 and anode 24 forming a triode assembly. The cathode heater is so arranged that the body of the cathode operates at a higher temperature than the head. The triode and multiplier assemblies are separated by a screen 25, 26 having an opening for the cathode head The triode assembly is utilized to produce oscillations which are communicated to one of two electrodes 12, 13 controlling the discharge to the electron multiplier, incoming signals being applied to the other electrode. An electrode 14 between the electrodes 12, 13 directs the electrons to the multiplier system.

Title: Improvements in and relating to hatch covers, especially for ships
IPC: B63B19/203
Filed: 1961-05-01
Abstract: 923,395. Hatch covers. GOTAVERKEN A.B. May 1, 1961 [May 5, 1960; Nov. 7, 1960], No. 15737/61. Class 113. A hatch cover comprises a number of sections grouped in hinged-together pairs, .e.g. 3, 4 and 5, 6 which for opening the hatch are moved on wheels 7 to a stowage space 8 defined by side frames which extend substantially to the same level as the hatch coaming 1. The first section, 3 or 5, of each pair is wider in the direction of stowing than the second section, 4 or 6, by an amount substantially corresponding to the height of the coaming. The side frames of the stowage 8 are provided with guide slots 11 and 12 which receive guide members 10, e.g. pins, fitted to the sections 3 and 5 respectively. The paired sections are connected together by pins 16, on the second section 4, which locate in slots 15, on the first section 5. The hatch is opened by a pulling cable 13, connected adjacent to the hinge arms of the furthestmost pair, 5 and 6, and passing a pulley 14 adjacent the hinged axis of the pair 3 and 4. The slots 11 and 12 are so disposed that upon opening the hatch the section 3 will pass over the slot 12 and it's pin 10 will locate in the slot 11 causing it to tip about the support member 9 to a vertical position, which movement simultaneously causes the following pair to be moved along, through rotation of the section 4 and the connection 15 and 16, until the pin 10 of the section 5 locates in the slot 12 to tip that section to a stowed vertical position. Movement in the opposite direction by a pulling cable (not shown) closes the hatch. The wheels 7 are eccentrically mounted so that the sections may be moved off seals. The pins 16 may be eccentrically mounted, or detachable. The sections may alternatively be pushed to the stowage space 8. A stowage space may be disposed at each end of the hatch, each arranged to accomodate a half of the total pairs of sections. A further embodiment describes the pairs of sections connected by links which have cam surfaces for tipping the sections.

Title: Improvements in or relating to change-speed mechanism, particularly for vehicles
IPC: F16H61/02
Filed: 1946-05-27
Abstract: 612,572. Controlling variable-speed gearing. MILLEDGE, S. Z. May 27, 1946, No. 16082. [Class 80 (ii)] In a variable-speed gear 11, restraining means for controlling the speed-changing means is provided by a fluid-pressure variablevolume device 29, 40 which is rendered responsive to the respective speeds of the input and output shafts 12, 14 by a primary pump 24 driven from the input shaft, and a plurality of secondary pumps 30, 31, 32 driven from the output shaft, the resisting means operating in accordance with the fluid pressure variations in the connection 29 between the primary and secondary pumps. In one embodiment in which the invention is applied to the control of an electrically-operated gear-box 11 having solenoids 15, 16, 17 manually energized by the switches 19, 20, 21, the position of a movable contact 43, which completes the respective circuits from the battery 22 is determined by the position of a piston 40 in a cylinder 29 which receives fluid from the primary pump 24 and is emptied of fluid by the secondary pumps 30, 31, 32, the number of which in operation depending on the position of the piston 40. As the discharge characteristics of the pumps are chosen so that they are proportional to the ratios provided by the gear-box, the position of the piston 40 will be such that contact is made with the plates 46, 47 or 48 only when the speeds of the input and output shafts are synchronous for the desired gear ratio, too high a relative speed resulting in excess fluid from the primary pump and therefore movement of the piston to the left to uncover the inlet to a further pump and so allow a change to a lower speed. For a neutral position with the driven shaft 14 stopped, the piston 40 is forced to the extreme left to uncover a byepass 39 to the reservoir 26 and is spring loaded by the spring 55 to allow the lowest gear to be used for moving the vehicle from rest. In a modification applied to a mechanically-operated change-speed mechanism, the piston-rod 41 interlocks the selector rods with a ball detent. In another modification for a two-speed gear, two secondary pumps are selectively in the fluid circuit and the difference in fluid-pressure resulting from asynchronism of the input and output shafts acts on a differential area piston valve motor to interlock the selector rods.

Abstract: 995,700. Semi-conductor devices. WESTING- HOUSE ELECTRIC CORPORATION. April 24, 1963 [May 9, 1962], No. 16183/63. Heading H1K. A solid circuit e.g. of germanium or silicon comprises a high resistivity semi-conductor substrate with a first lower resistivity layer and a second intermediate resistivity layer of one conductivity type epitaxially grown on it and together forming the collector region of a junction transistor of the circuit. In one example a silicon body 12 of intrinsic or high resistivity P- or N - type material is provided with two successive N- or P-type layers of silicon by hydrogen reduction of doped silicon tetrahalide. Suitable dopants include indium, gallium, aluminium and boron for P layers, and antimony and phosphorus for N layers. The concentration of dopant is reduced for the formation of the second epitaxial layer 116 after the formation of the first 114. The central portion of the layers may be removed by etching through a wax mask to form separate pairs of layers connected only by the high resistivity substrate 12. Selective diffusion of a P-type layer 22, 22a into the N-type epitaxial regions 116 and 116a through gaps in a silicon oxide coating provide bases of transistors and N- type zones are then formed to provide emitters 28, 28a and collector contacts 30, 30a. Alternatively these emitters and collector contacts are formed by alloying on gold-antimony foils. Specifications 889,058 and 913,674 are referred to.

Drawings to Specification, Class 39 (iii)] In the production of machine parts from semi-conductive ceramic material, e.g. gas turbine blades, the sintering temperature is produced in the ceramic by supplying electrical energy directly thereto at least during the final phase of the heating either by passage of current therethrough or by dielectric heating, the energy supply circuit having means for observing a change in an electrical characteristic of the ceramic part, the current being cut off when the means indicate a predetermined value. When current is passed through the part, the circuit includes an ammeter and voltmeter, and current is cut off when the resistance of the .part reaches a predetermined value corresponding to the required mechanical and thermal properties of the part, e.g. when its conductivity is at a maximum or before its conductivity decreases. When dielectric heating is used, a tuning indicator in the circuit shows a change of conductivity of the part, the electrodes being arranged to create a uniform temperature therein.
